  • Integrate Retrieval-Augmented Generation (RAG) architectures with vector databases (e.g., FAISS, Milvus) to support context-aware responses and tool routing.

  • Engineer prompts and multi-step reasoning chains for LLMs in agent-based environments.

  • Deploy and optimize open-source LLMs using vLLM , Triton , or Ollama , ensuring low-latency inference at scale.

  • Translate core NLP capabilities into production-ready agent behaviors, collaborating with engineering and product teams.

  • Stay at the forefront of agentic AI research , contributing to internal frameworks and incorporating cutting-edge ideas from open source and academia.

  • Present project outcomes and model behaviors to both technical and non-technical stakeholders to guide product strategy.

  • 2+ years of experience in AI or NLP-focused roles , including production deployment of LLM-driven systems.

  • Proficiency in Python and libraries such as Transformers , LangGraph , LangChain , and PyTorch .

  • Strong knowledge of prompt engineering , context management , and multi-agent orchestration .

  • Hands-on experience deploying and scaling LLMs in production environments.

  • Familiarity with retrieval mechanisms , vector search , and memory architectures in agent workflows.
